OIL-BURNER.

To all whom it may concern:

Be it known that I, Moses L. Benson, citizen of the United States, residing at Grlasco, in the county of Cloud and State of Kansas, have invented certain new and. usefullmproveinents in Oil-Burners, of which the following is a specification.

My invention relates to burners -for burning hydrocarbon, such as crude oil, kerosene, gasolene, etc, and the object of the invention is to provide a very simple, durable and effective burner of this character particularly adapted for use with cooking or heating stoves, and so arranged that it may be easily put in place within an ordinary stove Without materially changing the stove or furnace to which it is applied.

A further'object is to provide a burner of such simplicity that the parts cannot get out of order and so constructed that the burner may be readily cleaned whenever desired.

With these and other objects in View as will morefully appear as the description proceeds, the invention consists of certainconstructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For-a full understanding of the invention, reference to be had to the following descripting: and accomianying drawing in which Figure is a sectional View of stove with my i. .proved burner in place therein, the burner being in section on a plane passing through the air chamhers; 2 is atransverse section of the tour the section lineextending between the P chambers; Fig. 3 is horizontal through the cap 10 above the nozzle section 9. F is a perspective View of the has-e L of theburner. Fig. 5 is. a perspective View of the nozzle cap. l? t? is a perspective view of the cover.

is about. equal to the internal diameter of the stove and the base 2 rests upon the grate bars thereof.

The base 2 is formed with a central gas generating chamber 5 the Walls of this chamber being preferably cast integral with the base. The base immediately beneath the chamber 5 is formed With the perforation 6 into which passes a supply pipe 7, and the upper Wall of the chamber 5 is perforated and screw-threaded for the reception of a nozzle 8. This nozzle is formed with a tip 9 which is removable so that the tip may be replaced when necessary. The upper end of the tip is formed with. radiating notches 9 A. ren'iovaole cap 10 rests upon the upper end of the tip, this cap being provided with radiating spaced lugs 11 so as to center the cap upon the tip and permit the gas from the nozzle to pass downwardly between the nozzle and the dmvnvmrdly extending inargin of the cap 10, the flames from the burn lflQ being directed against the Walls of the generating chamber 5.

Located atintervals around the generating chamber 5 and prezt'erahly hetweenthe generating chamber and the upstanding rim 3,a.re

air chamber sections 12, these chamber :icns beingpreferably cast inone piece 1 he hase somewhat above gas generating chain her a cover which is niade Mia-whatb in internal diameter i the exit nal diameter of the gas gen- 1 l l ori'ned integral With "e he ellotical air chamber secd to fit upon and v. e uauons oi the an chamber sec- 4" fitting down upon the shoulders sur ending thenipples 1%. It Will be seen I ;this cover istherefore supported upon a; oyer the noznle S and the gen" y heavy casting, this cover he 1 circular 1n form and bee timer edges of the chamber sec-' the upper ends of the chamber sections 12. The chamber sections 17 have outlet openings 18 on their inner walls, these outlet openin s being all directed toward the nozzle 8. it is to be noted that the lower edge of the concavo-convex cover 16 is supported above the'upper edge of the upstanding wall 3 so that the flames, downwardly directed by the cover, which acts as a flame deflector, are forced downward beneath the lower edge of the cover and then out-ward between and around the air chambers. In order to permit the cover to be readily removed it is provided with a lug 19 upon its upper face. Normally however, the cover remains solidly in place upon the burner, the cover having such weight that it is not readily removed.

The operation of my invention .will be obvious from what has gone before. Oil is permitted to flow into the generating chamber 5, and the heat of the flames directed downward upon the generating chamber by the inverted cap 8 causes the oil within the chamber 5 to vaporize, the vapor passing up from the nozzle and being ignited. As it passes from the cap, the flames are directed downward and outward by the rounded outer face of the generating chamber and by the concavo-convex cover 16 and pass downward between the cover and the generating chamber and then upward and outward between the air chambers 12, thus thoroughly heating the air in the air chambers. Thus the air which is directed toward the nozzle and the vapor which passes out of the nozzle are both thoroughly heated and put in the best condition for combination. When the burner is first started suliicient oil is poured into the pan formed by the base 2 and the oil is ignited. The oil in the pipe 7 is then allowed to flow into the chamber 5 and the ignited oil in the pan surrounding the chamber 5 heats the chamber sufiiciently "to start vaporization. After that the burner takes care of itself.

I have found in practice that a burner of this character gives out a very large degree of heat with a relatively small consumption of fuel. It has no complicated or delicate parts and hence can stand rough usage much better than ordinary oil burners. The large amount of relatively thick metal exposed to the heat acts to vaporize the oil very quickly and prevents/this vaporization from ceasing with slight fluctuations in the oil supply.

By removing the cover the upper face of the base may be readily cleaned or the tip removed andreapplied. There is very little chance for the lodgment of soot, and if the parts do become coated with soot. the soot may be easily removed and this without the necessity of taking the burner out of the stove, "furnace or heater to which it is applied.

oans-ea That I claim is:

it. An oil burner including a base having the form of a pan, a gas generating chamber forming part of the base, a supply pipe opening into the gas generating chamber, a nozzle projecting from the chamber opposite to the supply pipe, a plurality of air chambers located around the generating chamber and having discharge openings, said air chambers opening upon the under side of the base, and a deflecting cover extending over the nozzle and supported upon the base and acting to direct the air from said air discharge openings toward the nozzle.

2. An oil burner including a base having the form of a pan, a gas generating chamber formed within the base, a fuel supply pipe opening into the gas generating chamber, an upwardly projecting nozzle extending from the chamber, a cap resting upon the upper end of the nozzle and deflecting the Vapor therefrom downward against the base, a plurality of air chambers mounted on the base and located at intervals around the gas chamber, each air chamber being formed with an outlet opening and a cover supported upon the base and extending over the gas generating chamber and inclosing the nozzle thereof, said cover acting to direct the air entering through the outlet openings of the air chambers toward the nozzle.

3. An oil burner including a base having the form of a pan, a gas generating chamber integral with the base and formedin the center thereof, a fuel supply pipe opening into the generating chamber, an upwardly projecting nozzle extending from the gas generating chamber, a deflecting cap on the nozzle, a plurality of air chambers formed integral with the base and located at intervals around the gas chamber, eachnof said air chambers being open at its lower end, and a concave-convex cover larger in diameter than the diameter of the generating chamber, said cover being provided at intervals with chamber sections completing the chamber sections carried upon the base, each of said chamber sections in the cover being provided with an inwardly directed opening.

4. An oil burner including a circular panshaped base having an annular marginal flange, a central gas generating chamber formed integral with the base and having a rounded upper wall, a nozzle projecting from the gas generating chamber and having a removable tip, a concavo-convex deflecting cap supported on the end of the nozzle, air chamber sections integral with the base and located at intervals around the gas generating chamber, said air chamber sections being open at their lower ends and at their upper ends, a concavo-convex cover less in diameter than the diameter of the panshaped portion of the base andhaving a plurality of air chamber sections formed inte In testimony whereof, I aflix my signature 'ral therewith and resting upon the air in presence of two Witnesses. c inmber sections first named, said last- MOSES L BULSON.
